Impact of endometritis on post-partum ovarian cyclicity in dairy cows (2019)
Journal Article
Mohammed, Z., Mann, G., & Robinson, R. (2019). Impact of endometritis on post-partum ovarian cyclicity in dairy cows. Veterinary Journal, 248, 8-13. https://doi.org/10.1016/j.tvjl.2019.03.008

Endometritis in dairy cows is a major global issue and has been associated with a decrease in reproductive performance. The aim of this study was to quantify the effect of endometritis (as defined by the presence of any abnormal vaginal discharge aft...

Milk progesterone on day 5 following insemination in the dairy cow: associated metabolic variables and reproductive consequences (2018)
Journal Article
Yan, L. Y., Robinson, R. S., Shi, Z. D., & Mann, G. E. (2018). Milk progesterone on day 5 following insemination in the dairy cow: associated metabolic variables and reproductive consequences. South African Journal of Animal Science, 48(2), 361-368. https://doi.org/10.4314/sajas.v48i2.17

Despite the importance of progesterone on the fertility of lactating dairy cows, the factors that affect post ovulatory progesterone concentration are still unclear. Thus, the aim of the present study was to identify factors associated with the post...

Physiological responses of cultured bovine granulosa cells to elevated temperatures under low and high oxygen in the presence of different concentrations of melatonin (2017)
Journal Article
Zeebaree, B. K., Kwong, W. Y., Mann, G. E., Gutierrez, C. G., & Sinclair, K. D. (2018). Physiological responses of cultured bovine granulosa cells to elevated temperatures under low and high oxygen in the presence of different concentrations of melatonin. Theriogenology, 105, https://doi.org/10.1016/j.theriogenology.2017.09.014

Our understanding of the effects of temperature on granulosa cell (GC) physiology is primarily limited to in vitro studies conducted under atmospheric (approx 20% O2) conditions. In the current series of factorial experiments we identify important ef...

Mathematical analysis of a model for the growth of the bovine corpus luteum (2013)
Journal Article
Prokopiou, S. A., Byrne, H. M., Jeffrey, M. R., Robinson, R. S., Mann, G. E., & Owen, M. R. (2014). Mathematical analysis of a model for the growth of the bovine corpus luteum. Journal of Mathematical Biology, 69, 1515-1546. https://doi.org/10.1007/s00285-013-0722-2

© 2013, Springer-Verlag Berlin Heidelberg. The corpus luteum (CL) is an ovarian tissue that grows in the wound space created by follicular rupture. It produces the progesterone needed in the uterus to maintain pregnancy. Rapid growth of the CL and pr... Read More about Mathematical analysis of a model for the growth of the bovine corpus luteum.

Reducing dietary protein in dairy cow diets: implications for nitrogen utilization, milk production, welfare and fertility (2013)
Journal Article
Garnsworthy, P., MANN, G., SINCLAIR, K., & SINCLAIR, L. (2014). Reducing dietary protein in dairy cow diets: implications for nitrogen utilization, milk production, welfare and fertility. animal, 8(2), 262-274. https://doi.org/10.1017/S1751731113002139

In light of increasing global protein prices and with the need to reduce environmental impact of contemporary systems of milk production, the current review seeks to assess the feasibility of reducing levels of dietary CP in dairy cow diets. At CP le... Read More about Reducing dietary protein in dairy cow diets: implications for nitrogen utilization, milk production, welfare and fertility.

The progesterone receptor antagonist, onapristone has differential effects on the timing and control of the luteolytic mechanism depending on timing of administration in sheep (2013)
Journal Article
Mann, G., Wathes, D., & Robinson, R. (2013). The progesterone receptor antagonist, onapristone has differential effects on the timing and control of the luteolytic mechanism depending on timing of administration in sheep.
